Description

一种配置下行多点传输的方法、 终端、 无线网络控制器 本申请要求于 2011年 9月 20日提交中国专利局、申请号为 201110279444.X、 发明名称为"一种配置下行多点传输的方法、终端、无线网络控制器"的中国专利 申请的优先权， 其全部内容通过引用结合在本申请中。 技术领域 本发明涉及通信技术领域， 尤其涉及一种配置下行多点传输的方法、 终端、 无线网络控制器。 背景技术
UMTS ( Universal Mobile Telecommunications System, 通用移动通信系统 ) 在 Release-5 ( R5 )版本中， 引入了 HSDPA (高速下行分组接入， High Speed Downlink Packages Access )技术。
HSDPA信道包括高速共享数据信道 ( HS-PDSCH, High Speed Physical Data Share Channel ) 以及相应的下行共享控制信道（HS-SCCH, High Speed Shared Control Channel )和上行专用物理控制信道 ( HS-DPCCH, High Speed Dedicated Physical Control Channel )。 下行共享控制信道（HS-SCCH )承载从 MAC-hs到终 端的控制信息， 包括移动台身份标记、 H-ARQ相关参数以及 HS-DSCH使用的传 输格式。 这些信息每隔 2ms从基站发向 UE ( User Equipment, 移动台或用户）。 上行专用物理控制信道（HS-DPCCH ) 则由移动台用来向基站报告下行信道质 量状况并请求基站重传有错误的数据块。 HSDPA技术中， 每个 UE配置的 HSDPA 服务小区仅有 1个， 当 UE移动而进行切换时， 需要网络侧发起切换流程以完成从 原 HSDPA服务小区到目标 HSDPA服务小区的切换。
随着 UMTS技术的不断演进， 在 UMTS R8引入了 DC-HSDPA ( Dual Cell HSDPA, 双小区 HSDPA )技术， 该技术的原理是， 当 UE在一个双小区覆盖的区 域内发起业务时， 网络侧可以将其配置为 DC-HSDPA , 此时 UE可以同时在两个 小区内接收 HSDPA业务， 因而峰值速率得到了提升。
如图 1所示， cell 1和 cell2都在 NodeBl下， 工作的频点是互为相邻频点的关 系， 两个小区的覆盖范围可以认为是一样的， 当 UE驻留在两个小区的覆盖范围 内， 就可以配置为 DC-HSDPA工作状态。
在最新的 UMTS标准演进中， 又引入了 HSDPA-MultiPoint-Tx ( HSDPA下行 多点传输）技术， 该技术的原理是， 当 UE在同频的多个小区覆盖区域内时， 网 络侧可以将其配置为 MP-Tx状态， 此时 UE可以同时在两个小区内接收 HSDPA业 务。
如图 1所示， cell l和 cell2的工作的频点是相同的， 根据两个小区是否在同一 个 NodeB (基站 )下， 可分为 Intra-NodeB MP-Tx (图 2 )和 Inter-NodeB Tx (图
3 )状态。
需要说明的是， HSDPA-MP-Tx和 DC-HSDPA以及类似的多载波技术不同之 处在于：
MP-Tx的多个 HSDPA 务 d、区是同频或邻频的小区， 这些小区可以在同一 个 NodeB上或相邻的 NodeB上；
DC-HSDPA以及类似的多载波技术中， HSDPA服务小区必须是邻频， 在同 一个 NodeB上， 具有相同的覆盖。
由此可见 MP-Tx的灵活性更大， 应用场景也相对较广泛。
需要注意的是， 图 2和图 3中 RNC、 NodeB、 UE是 UMTS技术中的定义的节 点， RNC ( Radio Network Controller, 无线网络控制器） 负责 UE的准入和 RRC ( Radio Resource Control,无线资源控制）配置等； NodeB负责 UE的下行 HSDPA 调度、 内环功率控制和不同 UE的优先级处理等。
无论是 DC-HSDPA还是 MP-Tx技术， 由于存在多个 HSDPA服务小区， 从移 动性和切换的角度， 需要定义主小区和辅小区。
以 DC-HSDPA技术为例， UE的 HSDPA服务小区为 cell 1和 cell 2, 此时可以定 义 cell 1 为 主 小 区 ， cell 2 为 辅 小 区 。 主 小 区 上 会 承 载 HS-SCCH/HS-PDSCH/HS-DPCCH信道和其他专用信道， 而辅小区仅承载 HS-SCCH/HS-PDSCH信道用于 HSDPA数传。 这样定义信道配置， 是因为 DC-HSDPA的两个小区具有相同的覆盖和定时偏差， 因而 UE在主小区建立了专 用信道用于同步后， 辅小区的信道定时参考可以依赖主小区内的定时， 因而辅 小区可以仅配置 HSDPA的下行信道。 HSDPA的上行反馈信道 HS-DPCCH采用联 合编码的方式，也即 UE在两个服务小区内接收数据的反馈信息和信道质量信息， 同在一条 HS-DPCCH上反馈， 该信道仅建立在主小区。
在 MP-Tx技术中， 因为 UE的 HSDPA服务小区并不具有相同的覆盖， 当 UE 进入多个同频小区的覆盖区域， 需要在这些 HSDPA服务小区分别建立 HS-SCCH/HS-PDSCH和其他专用信道。 HS-DPCCH信道仍然采用联合编码的方 式， 但是在 Inter-NodeB MP-Tx下， 主小区和辅小区都需要去接收 HS-DPCCH以 便获得下行数据的反馈信息。
根据 MP-Tx应用的连接态， 可以分为 CELL_DCH MP-Tx和 CELL_FACH MP-Tx。
CELL_DCH下的 MP-Tx操作， 现有技术有比较好的小区测量、 上报以及专 用信令配置等流程， 因而可以认为现有技术只需要较少的修改就可以支持 CEL—DCH MP-Tx。
而 CELL_FACH下， 现有技术中仅在小区重选过程中才会涉及到小区测量， 目前缺少在 CELL_FACH MP-Tx中测量、 上报以及配置的完整的技术解决方案。 发明内容 本发明实施例所要解决的技术问题是， 提供一种在 CELL_FACH MP-Tx下 进行小区测量， 上报以及配置的技术解决方案。

具体实施方式 下面将结合本发明实施例中的附图， 对本发明实施例中的技术方案进行清 楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而不是 全部的实施例。 基于本发明中的实施例， 本领域普通技术人员在没有作出创造 性劳动前提下所获得的所有其他实施例， 都属于本发明保护的范围。
本发明提供的以下实施例， 既适用于 UMTS 系统， 也适用于 TD-SCDMA ( Time Division-Synchronous Code Division Multiple Access , 时分同步码分多址 ) 系统。
在 MP-Tx技术中， 由于存在多个 HSDPA服务小区， 从移动性和切换的角 度， 需要定义主小区和辅小区， 这样可以更好地继承已有的移动性流程， 从而 减少由于新技术引入的实现复杂度。
在 MP-Tx技术中， 因为 UE的 HSDPA服务小区并不具有相同的覆盖， 当 UE 进入多个同频小区的覆盖区域， 需要在这些 HSDPA服务小区分别建立 HS-SCCH/HS-PDSCH和其他专用信道， HS-DPCCH信道采用联合编码的方式。 在 Inter-NodeB MP-Tx下， 主小区和辅小区都需要去接收 HS-DPCCH以便获得 下行数据的反馈信息。
参见图 4, 为本发明提供的 CELL_FACH MP-Tx应用场景示意图。
如图所示， 在网络中有三个基站， 分别是 NodeBl, NodeB2, NodeB3 , 每个 基站下面分别又有三个小区， 这些小区工作的频点相同或者是邻频。
假设 UE当前处于 CELL_FACH状态， 图中椭圆形的阴影区域为软切换区， 在 MP-Tx模式下， UE在这些区域中移动时， 可以同时在相关的小区内接收下 行 HSDPA数据。 比如当 UE在 cell 4和 cell 5的软切换区时， UE可以同时配置 在 cell 4和 cell 5内接收 HSDPA数据。 当 UE在这几个软切换区移动时，会进行 移动性过程， 从而保证能连续、 无缝地处于 CELL_FACH MP-Tx状态， 从而能 保证用户一直享受速率的体验。
本发明中，为了为驻留在某一主小区 UE配置 CELL_FACH状态下的下行多 点传输辅小区， 主要通过无线网络控制器和终端来实现。 以下将分别从无线网 络控制器侧和终端侧介绍本发明提供的配置下行多点传输的方法的实现过程。
参见图 5 ,为本发明提供的为终端配置下行多点传输的方法实施例一的流程 示意图。
本实施例将描述无线网络控制器指示终端进行 CELL_FACH状态下的下行 多点传输辅小区配置的方法流程， 此时终端驻留在如图 4所示的主小区 cell5 , 且处于 CELL_FACH状态。 具体方法流程如下：
步骤 100,无线网络控制器指示终端筛选 CELL_FACH下行多点传输的候选 辅小区；
步骤 101 , 无线网络控制器接收终端上报的候选辅小区， 以及其是否具备 CELL_FACH下行多点传输的能力； 步骤 102,无线网络控制器在终端上报了具备 CELL_FACH下行多点传输的 能力时， 向终端发送下行多点传输配置指示， 指示终端完成 CELL_FACH下行 多点传输的辅小区的配置。
本发明实施例提供了网络侧的无线网络控制器指导终端进行 CELL_FACH MP Tx 配置的完整流程， 可以在不影响终端在现有 CELL_FACH模式下的较低 电量消耗， 较少信令开销的前提下， 实现高效和灵活的 CELL_FACH MP Tx 配 置， 有利于改善 CELL_FACH模式下小区边缘的终端的数据吞吐速率， 提升用 户的体马全。
在本发明实施例中， 无线网络控制器指示终端筛选候选的 CELL_FACH下 行多点传输辅小区的方式可以是在终端驻留的主小区 （cell5 )发送的广播消息 中， 指示终端筛选同频或邻频的邻居小区作为 CELL_FACH下行多点传输的候 选辅小区。 该广播消息中携带有指示终端对邻居小区进行测量以筛选同频或邻 频邻居小区的多点小区测量指示信息。 可选地， 该广播消息中还携带有测量门 限和 /或测量时长； 测量门限用于指示终端筛选邻居小区后， 筛选邻居小区中与 主小区的信道质量差在该测量门限范围中的邻居小区作为 CELL_FACH下行多 点传输的候选辅小区； 测量时长用于指示终端筛选 CELL_FACH下行多点传输 的候选辅小区的有效的时间范围。
具体地， 无线网络控制器（RNC )在 cell 5 的广播消息中， 携带用于指示 UE筛选较好的同频或邻频邻居小区以满足 CELL_FACH MP-Tx的需要的指示 信息。 该指示信息包含的内容如下：
MP小区测量指示信息 （必选）， 比如配置为 lbit, 当值为 1时， RNC指示 UE需要进行 MP小区测量；
测量门限（可选）， 比如配置为 0.5dB , 也即 UE测量完邻区的频点， 确定 服务小区后， 需要判断， 如果同频或频频邻居小区与当前主小区之间的信号质 量差值在 0.5dB 以内时， 就认为该同频或邻频邻居小区可以和当前主小区进行 MP-Tx协作；
测量时长（可选）， 比如配置为 100ms , 该参数配合 "测量门限" 使用， 也 即需要在 100ms 内都满足上述条件， 才可以认为该同频或邻频邻居小区可以和 当前主小区进行 MP-Tx协作。 满足条件的同频或邻频邻居小区则作为候选辅小 区。 本领域技术人员可以根据上述描述理解 RNC 如何指示终端筛选 CELL_FACH下行多点传输的候选辅小区， 为便于本领域技术人员进一步理解， 以图 4为例进行说明。 UE需要测量邻居小区 cell 4, cell3 , cell3的频点， 此时 RNC可以在广播消息中携带 "指示信息"， 包含内容为 "MP小区测量指示信息 为 1 , 测量门限为 0.5dB, 测量时长为 100ms" , 那么当 UE测量邻居小区的频点 时， 假如仅 cell3和 cell4在 100ms内测量都满足规定的门限， 此时 UE就认为 cell 3和 cell 4是候选辅小区。
终端在接收到 RNC发送的指示其进行候选辅小区筛选的指示消息后， 会进 行筛选并上报候选辅小区， 并且还会上报其是否具备 CELL_FACH下行多点传 输的能力， 在上报是否具备 CELL_FACH下行多点传输的能力的同时或之后， 还可以将其是否具备连接态读取系统信息的能力上报至无线网络控制器。 该过 程在后续的实施例中将做详细说明， 此处先介绍无线网络控制器接收终端上报 的候选辅小区和相关的能力之后， 如何指示终端完成 CELL_FACH下行多点传 输的辅小区的配置。
总的来说， 根据终端上报的其是否具备 CELL_FACH下行多点传输的能力 和是否具备连接态读取系统信息的能力的情况， RNC有两种方式指示终端完成 CELL_FACH下行多点传输的辅小区的配置。
其一： RNC可以在向终端发送的下行多点传输配置指示中携带 CELL_FACH 下行多点传输辅小区配置信息， 指示终端按照该 CELL_FACH下行多点传输辅 小区配置信息， 完成 CELL_FACH下行多点传输的辅小区的配置。 下行多点传 输配置指示可在 RNC 发给终端的下行 RRC 信令中携带， 比如携带在 CELL UPDATE CONFIRM (小区更新确认 )消息中。 这里所称的辅小区从终端上报的 候选辅小区中挑选的。 RNC可以根据终端上报的候选辅小区是否支持 MP-Tx能 力， 该候选辅小区的负载情况来进行挑选。
其二： RNC向终端发送下行多点传输配置指示中携带允许配置 CELL_FACH 下行多点传输辅小区的指示信息， 以及 CELL_FACH下行多点传输小区的标识 信息， 指示终端到标识信息对应的辅小区中读取 CELL_FACH下行多点传输的 辅小区配置信息以完成 CELL_FACH下行多点传输的辅小区的配置。 这里所称 的辅小区从终端上报的候选辅小区中挑选的。 RNC可以根据终端上报的候选辅 小区是否支持 MP-Tx能力， 该候选辅小区的负载情况来进行挑选。 需要说明的是， 当终端联合和分别上报其既具备 CELL_FACH下行多点传 输的能力又具备连接态读取系统信息的能力时， RNC可以采取上述两种方式中 的任意一种方式指示终端完成 CELL_FACH下行多点传输的辅小区的配置。
而当终端上报其具备 CELL_FACH下行多点传输的能力但不具备连接态读 取系统信息的能力时， RNC采用第一种方式指示终端完成 CELL_FACH下行多 点传输的辅小区的配置。
另外， 如果无线网络控制器要发起基站和终端同步配置的流程， RNC需要 指示基站和终端配置生效的时间， 该配置生效时间用于指示终端在配置生效时 间内， 按照 RNC下发的 CELL_FACH下行多点传输辅小区配置信息， 与基站同 步完成 CELL_FACH下行多点传输的辅小区的配置。
反之， 如果无线网络控制器发起基站和终端异步配置的流程， 也即指示终 端自行决定配置生效时间， 以在其自行决定的配置生效时间内， 按照 CELL_FACH下行多点传输辅小区配置信息， 完成 CELL_FACH下行多点传输 的辅小区的配置。
对于终端具备连接态读取系统信息的能力的情况， 无线网络控制器还可以 向终端发送系统信息读取时间和配置生效时间， 指示终端在系统信息读取时间 内到标识信息对应的辅小区中读取 CELL_FACH下行多点传输辅小区配置信息， 并在配置生效时间内完成 CELL_FACH下行多点传输的辅小区的配置。
以上 RNC指示终端完成 CELL_FACH下行多点传输的辅小区的配置的流程 参见图 6。图 6为本发明提供的为终端配置下行多点传输的方法实施例二的流程 示意图。
本实施例中描述 UE联合上报其具备 CELL_FACH下行多点传输的能力（以 下称支持 "CELL_FACH MP-Tx" )和具备连接态读取系统信息的能力后， RNC 指示终端完成 CELL_FACH下行多点传输的辅小区的配置的流程。 这里所称的 联合上报， 是指终端支持 "CELL_FACH MP-Tx" 和具备连接态读取系统信息的 能力两者之间是绑定关系， 终端上报其具备其中一种能力， 则表明其具备另一 种能力， 否则就都不具备。
本实施例方法流程如下：
步骤 200, RNC接收 UE联合上报的候选辅小区和其具备的能力信息， RNC 对 UE上报的能力信息进行判断。 步骤 201 , RNC判断终端支持 "CELL_FACH MP-Tx"并具备连接态读取系 统信息的能力。
此时， 如果 RNC要发起同步配置流程， 则其需要指示 NodeB和 UE配置生 效的时间
如果配置生效时间要大于 UE读取邻区 MP-Tx配置的系统信息的时间， 则 及可以转到步骤 202也可以转到步骤 203。这样一方面是保证网络侧有较大的配 置灵活性， 另一方面是保证 UE有充足的时间完成邻区 MP-Tx配置的系统信息 的读取， 提高配置 CELL_FACH MP-Tx的成功率， 减少专用信令开销；
反之， 则转到步骤 202;
举例来讲， UE支持 "CELL_FACH MP-Tx" , RNC要发起同步配置流程， RNC指示给 NodeB和 UE配置生效的时间为 200ms以后， 并且 UE读取邻区 MP-Tx配置的系统信息的时间为 150ms ,此时应该转到步骤 202或步骤 203; 反 之， RNC指示给 NodeB和 UE配置生效的时间为 100ms以后， 并且 UE读取邻 区 MP-Tx配置的系统信息的时间为 150ms , 则转入步骤 202。
或者， RNC可以根据自身策略， 对不同 UE的配置区别对待， 比如部分 UE 的配置转到步骤 202, 部分 UE的配置转到步骤 203。 需要说明的是步骤 202由 于采用专用信令配置， 可靠性较高， 配置时间较短， 但由于携带了完整的 CELL_FACH MP-Tx配置信息， 信令开销较大； 步骤 203由于是网络侧指示 UE 读取系统信息， 可靠性较低， 配置时间取决于 UE读取系统信息的时间， 但由于 系统信息是小区公共发送的， 因而节省了专用信令配置的开销。
步骤 202, RNC在下行的 RRC信令中携带 MP-Tx辅小区配置信息。
UE收到配置信息后完成 CELL-FACH配置， 并回复配置完成响应消息。 流 程结束。
这里所称的 MP-Tx辅小区配置信息包括： 如 H-RNTI配置信息， 用于指导 终端进行 H-RNTI配置；下行扰码配置信息，用于指导终端区分接收数据的小区； HS-SCCH信道配置信息， 包括功率偏移信息等； 以及其他下行 HSDPA配置信 息， 比如下行是否采用高阶调制方式配置、 下行传输块大小配置表格等等。
步骤 203 , RNC在下行 RRC信令中， 携带是否配置 MP的指示信息， 以及 MP辅小区的标识信息， 比如小区扰码。
举例来讲， 比如在步骤 200中， RNC接收 UE上报的候选辅小区为 cell3和 cell4,但 RNC仅允许 cell3可以和当前主小区 cell5进行 CELL_FACH MP-Tx协 作， 也即仅允许 cell3配置为 cell5的辅小区， 此时 RNC应该在向终端发送的下 行 RRC信令中，携带：允许配置 CELL_FACH MP-Tx; 以及 CELL_FACH MP-Tx 辅小区是 cell 3的指示。
终端在接收上述指示后完成 CELL_FACH MP-Tx配置的过程在后续的实施 例中再进行描述。
上述实施例描述了终端联合上报其具备能力的情况下， RNC指导终端进行 CELL_FACH MP-Tx配置的过程， 以下将介绍终端分别上报其具备能力的情况 下， RNC如何指导终端进行 CELL_FACH MP-Tx配置的过程。
参见图 7,图 7为本发明提供的为终端配置下行多点传输的方法实施例三的 流程示意图。
步骤 300, RNC分别接收 UE上报的候选辅小区和其具备的能力信息， RNC 对 UE上报的能力信息进行判断。
步骤 301 , RNC判断终端支持 "CELL_FACH MP-Tx"并具备连接态读取系 统信息的能力。
此时， 如果 RNC要发起同步配置流程， 则其需要指示 NodeB和 UE配置生 效的时间。
如果配置生效时间要大于 UE读取邻区 MP-Tx配置的系统信息的时间， 则 及可以转到步骤 303也可以转到步骤 304。这样一方面是保证网络侧有较大的配 置灵活性， 另一方面是保证 UE有充足的时间完成邻区 MP-Tx配置的系统信息 的读取， 提高配置 CELL_FACH MP-Tx的成功率， 减少专用信令开销；
反之， 则转到步骤 304;
举例来讲， UE支持 "CELL_FACH MP-Tx" , RNC要发起同步配置流程， RNC指示给 NodeB和 UE配置生效的时间为 200ms以后， 并且 UE读取邻区 MP-Tx配置的系统信息的时间为 150ms ,此时应该转到步骤 303或步骤 304; 反 之， RNC指示给 NodeB和 UE配置生效的时间为 100ms以后， 并且 UE读取邻 区 MP-Tx配置的系统信息的时间为 150ms , 则转入步骤 303。
或者， RNC可以根据自身策略， 对不同 UE的配置区别对待， 比如部分 UE 的配置转到步骤 303 , 部分 UE的配置转到步骤 304。 需要说明的是步骤 303由 于采用专用信令配置， 可靠性较高， 配置时间较短， 但由于携带了完整的 CELL_FACH MP-Tx配置信息， 信令开销较大； 步骤 304由于是网络侧指示 UE 读取系统信息， 可靠性较低， 配置时间取决于 UE读取系统信息的时间， 但由于 系统信息是小区公共发送的， 因而节省了专用信令配置的开销。
步骤 302, RNC判断终端支持 "CELL_FACH MP-Tx" , 但不具备连接态读 取系统信息的能力， 此时转到步骤 303。
步骤 303 , RNC在下行的 RRC信令中携带 MP-Tx辅小区配置信息。
UE收到配置信息后完成 CELL-FACH配置， 并回复配置完成响应消息。 流 程结束。
这里所称的 MP-Tx辅小区配置信息包括： 如 H-RNTI配置信息， 用于指导 终端进行 H-RNTI配置；下行扰码配置信息，用于指导终端区分接收数据的小区； HS-SCCH信道配置信息， 包括功率偏移信息等； 以及其他下行 HSDPA配置信 息， 比如下行是否采用高阶调制方式配置、 下行传输块大小配置表格等等。
步骤 304, RNC在下行 RRC信令中， 携带是否配置 MP的指示信息， 以及 MP辅小区的标识信息。
举例来讲， 比如在步骤 300中， RNC接收 UE上报的候选辅小区为 cell3和 cell4,但 RNC仅允许 cell3可以和当前主小区 cell5进行 CELL_FACH MP-Tx协 作， 也即仅允许 cell3配置为 cell5的辅小区， 此时 RNC应该在向终端发送的下 行 RRC信令中，携带：允许配置 CELL_FACH MP-Tx; 以及 CELL_FACH MP-Tx 辅小区是 cell 3的指示。
终端在接收上述指示后完成 CELL_FACH MP-Tx配置的过程在后续的实施 例中再进行描述。
上述实施例描述了终端分别上报其具备能力的情况下， RNC指导终端进行 CELL_FACH MP-Tx配置的过程。
上述图 6 和图 7 所示的实施例介绍了 RNC 采用两种方式指示终端进行 CELL_FACH MP-Tx配置的过程， RNC采用第二种方式， 也即指示终端去辅小 区中读取系统信息进行 CELL_FACH MP-Tx配置的方法还可以更加优化。
具体地， RNC还在下行多点传输配置指示中携带定时器， 或通过下行无线 资源控制信令向终端发送定时器， 以指示终端在定时器超时前保留其读取 CELL_FACH 下行多点传输辅小区配置信息。 这种方式可以避免终端重复读取 CELL_FACHMP T-x配置信息， 以节约配置时间。 具体实现过程中， 可以对上述 步骤 203或者步骤 304中 RNC发送的下行 RRC信令进一步改进，使该 RNC不 但携带是否配置 MP的指示信息， 以及 MP辅小区的标识信息，还携带一个定时 器 Tmp给 UE, 或者单独发送一个携带定时器的下行 RRC信令给 UE, 以指示 UE在定时器超时前保留其读取 CELL_FACH下行多点传输辅小区配置信息。
以上实施例描述了无线网络控制器为终端配置下行多点传输的方法的具体 实现过程， 实施该方法， 可以在不影响终端在现有 CELL_FACH模式下的较低 电量消耗， 较少信令开销的前提下， 实现高效和灵活的 CELL_FACH MP-Tx 配 置， 有利于改善 CELL_FACH模式下小区边缘的终端的数据吞吐速率， 提升用 户的体验
以下将介绍终端一侧配置下行多点传输的方法的实施例。
参见图 8,为本发明提供的终端配置下行多点传输的方法实施例一的流程示 意图。
本实施例将描述终端进行 CELL_FACH状态下的下行多点传输辅小区配置 的方法流程， 此时终端驻留在如图 4所示的主小区 cell5 , 且处于 CELL_FACH 状态。 具体方法流程如下：
步骤 400,终端接收无线网络控制器指示其筛选 CELL_FACH下行多点传输 的候选辅小区的指示；
步骤 401 , 终端根据无线网络控制器的指示筛选符合条件的辅小区； 步骤 402,终端将候选辅小区， 以及自身是否具备 CELL_FACH下行多点传 输的能力上报给无线网络控制器；
步骤 403 , 终端接收并根据无线网络控制器发送的下行多点传输配置指示， 完成 CELL_FACH下行多点传输的辅小区的配置。
需要说明的是， 在上述步骤 401 中， 终端根据无线网络控制器的指示筛选 符合条件的辅小区， 包括：
终端接收小区的广播消息， 且该广播消息中携带有多点小区测量指示信息 时， 根据多点小区测量指示信息， 对邻居小区进行测量以筛选邻居小区。
终端在广播消息还进一步包括测量门限和测量时长时， 在筛选完邻居小区 后， 在测量时长指示的有效的时间范围内， 在邻居小区中筛选与主小区的信道 质量差在该测量门限范围中的邻居小区作为 CELL_FACH下行多点传输的候选 辅小区。 在上述步骤 402 中， 终端在上行无线资源控制信令中将候选辅小区上报给 无线网络控制器。 具体实现过程中， UE在上行 RRC信令中将其筛选的候选辅 小区上报给 RNC, 比如可以在小区更新消息或测量报告消息中增加满足候选辅 小区的标识信息。
在步骤 402中， 终端还可以将其是否具备 CELL_FACH下行多点传输的能 力和是否具备连接态读取系统信息的能力联合或分别上报给无线网络控制器。 该两个能力用于后续网络侧配置 CELL_FACH MP-Tx的判决。 这两个能力上 4艮 可遵循如下规则：
规则 1 : "是否具备连接态读取系统信息的能力" 可以和 "是否具备 CELL_FACH MP-Tx的能力"进行绑定，也即当 UE支持 "CELL_FACH MP-Tx" 时， UE也应该具备 "连接态读取系统信息" 的能力， 否则 UE都不支持这两个
- , ·
f]匕刀，
规则 2: "是否具备连接态读取系统信息的能力"和"是否具备 CELL_FACH MP-Tx的能力"之间没有绑定的关系， UE根据自身是否支持这两个能力单独进 行上报。
以图 4为例，假如采用规则 2,该 UE可能会上报支持" CELL_FACH MP-Tx" 能力， 上报不支持 "连接态读取系统信息" 能力。
以上描述了 RNC有两种方式指示终端完成 CELL_FACH下行多点传输的辅 小区的配置。
针对这两种不同的指示方式， 终端完成 CELL_FACH下行多点传输的辅小 区的配置的方式不同。
针对第一种方式， 终端接收无线网络控制器向终端发送的下行多点传输配 置指示中携带的 CELL_FACH 下行多点传输辅小区配置信息， 按照该 CELL_FACH下行多点传输辅小区配置信息完成 CELL_FACH下行多点传输的 辅小区的配置。
在第一种方式中， 如果终端还接收无线网络控制器向其发送配置生效时间； 则终端在配置生效时间内， 按照 CELL_FACH下行多点传输辅小区配置信息， 与基站同步完成 CELL_FACH下行多点传输的辅小区的配置。
如果终端接收无线网络控制器向其发送自行决定配置生效时间的指示； 则 终端在其自行决定的配置生效时间内， 按照 CELL_FACH下行多点传输辅小区 配置信息， 完成 CELL_FACH下行多点传输的辅小区的配置。
具体地， 参见图 9, 为本发明提供的终端配置下行多点传输的方法实施例二 的流程示意图。
本实施例包括：
步骤 500, UE接收 RNC在下行的 RRC信令中携带 MP-Tx辅小区配置信息。 步骤 501 , UE收到配置信息后完成 CELL-FACH配置。
步骤 502 , UE返回 RRC配置完成消息给 RNC，指示配置 CELL_FACH MP-Tx 成功。
流程结束。
针对第二种方式， 终端接收无线网络控制器向终端发送的下行多点传输配 置指示中携带的允许配置 CELL_FACH下行多点传输辅小区的指示信息， 以及 CELL_FACH 下行多点传输小区的标识信息， 到标识信息对应的辅小区中读取 CELL_FACH下行多点传输的辅小区配置信息以完成 CELL_FACH下行多点传 输的辅小区的配置。
在第二种方式下， 如果终端还接收无线网络控制器向其发送的系统信息读 取时间和配置生效时间； 则终端在系统信息读取时间内到标识信息对应的辅小 区中读取 CELL_FACH下行多点传输辅小区配置信息， 并在配置生效时间内完 成 CELL_FACH下行多点传输的辅小区的配置。
具体地， 参见图 10, 为本发明提供的终端配置下行多点传输的方法实施例 三的流程示意图。
本实施例包括：
步骤 600, UE接收 RNC在下行 RRC信令中携带的是否配置 MP的指示信 息， 以及 MP辅小区的标识信息。
步骤 601 , UE收到下行 RRC信令后，如果有指示配置 CELL_FACH MP-Tx 和辅小区标识信息，此时 UE需要到对应辅小区的广播消息中读取 CELL_FACH MP-Tx配置信息。
举例来讲， 比如 RNC指示了辅小区为 cell 3 , 此时 UE应该去读取 cell 3中 包含 CELL_FACH MP-Tx配置的系统信息。
步骤 602 , 如果配置成功， 则 UE返回 RRC配置完成消息给 RNC , 指示配 置 CELL_FACH MP-Tx成功； 流程结束。 步骤 603 , 如果配置失败， 则 UE返回 RRC配置完成消息给 RNC, 携带 MP辅小区配置失败指示，此时 UE回退到单小区 CELL_FACH配置，流程结束。
上述图 10所示的实施例介绍了采用 RNC指示终端去辅小区中读取系统信 息进行 CELL_FACH MP-Tx配置的方法流程， 该方法流程还可以更加优化。 其 优化方式是： 无线网络控制器还可以在其向终端发送的下行多点传输配置指示 中携带定时器， 或通过下行无线资源控制信令向终端发送定时器 Tmp, 终端还 接收无线网络控制器发送的定时器；并在定时器超时前保留其读取 CELL_FACH 下行多点传输辅小区配置信息。
具体地， UE收到 RNC发送的定时器后， 如果已经保存了 MP-Tx辅小区的 配置信息 （去 RNC指定的辅小区中读取的）， 那么 UE可以在 Tmp超期前一直 保存该 MP-Tx辅小区的信息， 这样在下次进行 CELL_FACH MP-Tx配置时， 就 可以节省配置时间和空口信令开销。
定时器 Tmp的使用规则如下：
启动时机： UE完成 CELL_FACH MP-Tx配置或离开 CELL_FACH MP-Tx 状态， 此时 UE和 RNC都需要启动该定时器。
启动 Tmp后，如果 Tmp没有超时。在如下条件下， UE应该停止并删除 Tmp, 并清除 MP-Tx辅小区配置：
UE从连接态进入到空闲态；
UE进行小区重选， 并且 RNC发生了改变。
启动 Tmp后， 如果 Tmp超时。 在如下条件下， UE应该清除 MP-Tx辅小区 配置：
UE退出 CELL_FACH MP-Tx状态；
主小区发生变化。
启动 Tmp 后， 如果 Tmp 没有超时。 如果网络侧要求 UE 再次配置 CELL_FACH MP-Tx , 并且指示的辅小区和 UE已保存配置的小区相同， UE需 要对比保存的配置信息是否发生变化：
如果 UE获取到该小区的 MP-Tx配置信息已经发生变化， 此时配置信息可 认为已失效， UE需要重新去读取邻区的包含 MP-Tx配置信息的系统信息； 如果 UE获取到该小区的 MP-Tx配置信息没有发生变化， 则 UE可认为已 保存的配置信息仍然有效。 由于是网络侧指示 UE读取系统信息， 可靠性较低， 配置时间取决于 UE读取系统信息的时间， 但由于系统信息是小区公共发送的， 因而节省了专用信令配置的开销"， UE 就可以不用读取邻区的系统信息从而使 得配置过程更加筒化。
举例来讲， 如图 4所示， 如果 UE已经通过去辅小区中读取 CELL_MP-Tx 配置信息的方法， 配置了主小区 cell 5和辅 ' j、区 cell 3进行 CELL_FACH MP-Tx 协作， 此时也配置了 Tmp ( 10s )。如果 UE移动到了 cell 1 , 此时从 CELL_FACH MP-Tx状态转换到 cell 1单小区状态， 然后 UE又移动到 cell 5和 cell 3的边缘， 那么如果又按照读取 CELL_MP-Tx配置信息的方式，在 Tmp没有超时的情况下， UE 可以直接使用之前保存的 cell 3 的配置信息， 这样可以大大减少配置 CELL_FACH MP-Tx的时间。
本发明实施例提供了在终端一侧完成 CELL_FACH模式下配置 MP-Tx的完 整流程， 在不影响现有 CELL_FACH下 UE较低电量消耗、 较少信令开销的前 提下， 实现高效和灵活的配置， 有利于地提升 CELL_FACH下用户的体验。 以上实施例分别介绍了从无线网络控制器侧和终端侧所进行的下行多点传 输的配置方法， 以下将介绍实现该方法的无线网络控制器和终端。
参见图 11 , 为本发明提供的无线网络控制器实施例一的组成示意图。
殳设此时终端驻留在如图 4所示的主小区 cell5 ,且处于 CELL_FACH状态。 本实施例中的无线网络控制器用于为该终端配置 CELL_FACH下行多点传输的 辅小区， 其具体包括：
筛选指示模块 10, 用于指示终端筛选 CELL_FACH下行多点传输的候选辅 小区；
信息接收模块 11 , 用于接收终端上报的候选辅小区， 以及其是否具备 CELL_FACH下行多点传输的能力； 可选地， 该信息接收模块 11还用于接收终 端上报的是否具备连接态读取系统信息的能力。
配置指示模块 12 , 用于在所述信息接收模块 11 接收到终端上报的具备 CELL_FACH下行多点传输的能力时， 向终端发送下行多点传输配置指示，指示 终端完成 CELL_FACH下行多点传输的辅小区的配置。
本发明实施例提供了网络侧的无线网络控制器用于指导终端进行 CELL_FACH MP Tx 配置， 可以在不影响终端在现有 CELL_FACH模式下的较 低电量消耗，较少信令开销的前提下，实现高效和灵活的 CELL_FACH MP Tx 配 置， 有利于改善 CELL_FACH模式下小区边缘的终端的数据吞吐速率， 提升用 户的体马全。
在本发明实施例中， 筛选指示模块 10具体用于在终端驻留的主小区发送广 播消息指示终端筛选同频或邻频的邻居小区作为 CELL_FACH下行多点传输的 候选辅小区。
参见图 12, 为本发明提供的无线网络控制器实施例二的组成示意图。
本实施例中描述筛选指示模块 10的具体组成， 包括：
测量指示单元 100, 用于在筛选指示模块 10发送的广播消息中携带多点小 区测量指示信息， 以指示终端对邻居小区进行测量以筛选邻居小区。
可选地， 筛选指示模块 10还包括：
门限指示单元 101 , 用于在筛选指示模块 10发送的广播消息中携带测量门 限， 以指示终端薛选邻居小区后， 薛选信道质量差在该测量门限范围中的邻居 小区作为 CELL_FACH下行多点传输的候选辅小区；
时长指示单元 102, 用于在筛选指示模块 10发送的广播消息中携带测量时 长， 以指示终端筛选 CELL_FACH下行多点传输的候选辅小区的有效的时间范 围。
具体地， 无线网络控制器（RNC ) 的筛选指示模块 10在 cell 5的广播消息 中， 携带用于指示 UE 筛选较好的同频或邻频邻居小区以满足 CELL_FACH MP-Tx的需要的指示信息。 其中， 门限指示单元 100在该指示信息中携带 MP 小区测量指示消息， 门限指示单元 101 在该指示信息中携带测量门限， 时长指 示单元 102在该指示信息中携带测量时长， 它们的含义分别如下：
MP小区测量指示信息 （必选）， 比如配置为 lbit, 当值为 1时， RNC指示 UE需要进行 MP小区测量；
测量门限（可选）， 比如配置为 0.5dB , 也即 UE测量完邻区的频点， 确定 服务小区后， 需要判断， 如果同频或频频邻居小区与当前主小区之间的信号质 量差值在 0.5dB 以内时， 就认为该同频或邻频邻居小区可以和当前主小区进行 MP-Tx协作；
测量时长（可选）， 比如配置为 100ms , 该参数配合 "测量门限" 使用， 也 即需要在 100ms 内都满足上述条件， 才可以认为该同频或邻频邻居小区可以和 当前主小区进行 MP-Tx协作。 满足条件的同频或邻频邻居小区则作为候选辅小 区。
本领域技术人员可以根据上述描述理解 RNC 如何指示终端筛选 CELL_FACH下行多点传输的候选辅小区， 为便于本领域技术人员进一步理解， 以图 4为例进行说明。 UE需要测量邻居小区 cell 4, cell3 , cell3的频点， 此时 RNC可以在广播消息中携带 "指示信息"， 包含内容为 "MP小区测量指示信息 为 1 , 测量门限为 0.5dB, 测量时长为 100ms" , 那么当 UE测量邻居小区的频点 时， 假如仅 cell3和 cell4在 100ms内测量都满足规定的门限， 此时 UE就认为 cell 3和 cell 4是候选辅小区。
终端在接收到 RNC发送的指示其进行候选辅小区筛选的指示消息后， 会进 行筛选并上报候选辅小区， 并且还会上报其是否具备 CELL_FACH下行多点传 输的能力和是否具备连接态读取系统信息的能力。 该过程在后续的实施例中将 做详细说明， 此处先介绍无线网络控制器接收终端上报的候选辅小区和相关的 能力之后， 如何指示终端完成 CELL_FACH下行多点传输的辅小区的配置。
总的来说， 根据终端上报的其是否具备 CELL_FACH下行多点传输的能力 和是否具备连接态读取系统信息的能力的情况， RNC有两种方式指示终端完成 CELL_FACH下行多点传输的辅小区的配置。 也即， RNC的配置指示模块 12具 体有两种实现方式：
参见图 13 , 为本发明提供的无线网络控制器实施例三的组成示意图。
本实施例描述 RNC的配置指示模块 12的第一种实现方式。
具体地， RNC的配置指示模块 12由配置信息指示单元 120组成， 该配置信 息指示单元 120 用于在向终端发送的下行多点传输配置指示中携带 CELL_FACH下行多点传输辅小区配置信息， 指示终端按照该 CELL_FACH下 行多点传输辅小区配置信息， 完成 CELL_FACH下行多点传输的辅小区的配置。
这里所称的辅小区从终端上报的候选辅小区中挑选的。
参见图 14, 为本发明提供的无线网络控制器实施例四的组成示意图。
本实施例描述 RNC的配置指示模块 12的第二种实现方式。
具体地， RNC的配置指示模块 12由配置允许指示单元 121和小区标识指示 单元 122组成。 该配置允许指示单元 121 , 用于向终端发送下行多点传输配置指 示中携带的允许配置 CELL_FACH下行多点传输辅小区的指示信息； 该小区标 识指示单元 122, 用于向终端发送 CELL_FACH下行多点传输小区的标识信息， 以指示终端到标识信息对应的辅小区中读取 CELL_FACH下行多点传输的辅小 区配置信息以完成 CELL_FACH下行多点传输的辅小区的配置。
这里所称的辅小区从终端上报的候选辅小区中挑选的。
需要说明的是， 当终端联合和分别上报其既具备 CELL_FACH下行多点传 输的能力又具备连接态读取系统信息的能力时， RNC可以采取上述如图 12和图 13 所示的两种配置指示模块 12 中的任一种配置指示模块 12 指示终端完成 CELL_FACH下行多点传输的辅小区的配置。
而当终端上报其具备 CELL_FACH下行多点传输的能力但不具备连接态读 取系统信息的能力时， RNC 采用第一种配置指示模块 12 指示终端完成 CELL_FACH下行多点传输的辅小区的配置。
参见图 15 , 为本发明提供的无线网络控制器实施例五的组成示意图。
本实施例提供的无线网络控制器中针对当终端上报其具备 CELL_FACH下 行多点传输的能力但不具备连接态读取系统信息的能力时， RNC采用第一种配 置指示模块 12指示终端完成 CELL_FACH下行多点传输的辅小区的配置的情况 下， 如果无线网络控制器要发起基站和终端同步配置的流程， 则在本实施例中， 无线网络控制器除了包括如图 11中的各个模块之外， 还包括：
生效指示模块 13 , 其用于向终端发送配置生效时间， 指示终端在配置生效 时间内， 按照 CELL_FACH下行多点传输辅小区配置信息， 完成 CELL_FACH 下行多点传输的辅小区的配置。
反之， 如果无线网络控制器要发起基站和终端异步配置的流程， 则上述生 效指示模块 13则用于向终端发送指示信息， 指示终端自行决定配置生效时间， 以在其自行决定的配置生效时间内， 按照 CELL_FACH下行多点传输辅小区配 置信息， 完成 CELL_FACH下行多点传输的辅小区的配置。
参见图 16, 为本发明提供的无线网络控制器实施例六的组成示意图。
本实施例提供的无线网络控制器中针对当终端上报其具备 CELL_FACH下 行多点传输的能力但不具备连接态读取系统信息的能力时， RNC采用第二种配 置指示模块 12指示终端完成 CELL_FACH下行多点传输的辅小区的配置的情况 下， 无线网络控制器除了包括如图 11中的各个模块之外， 还包括：
读取指示模块 14, 用于向终端发送系统信息读取时间， 指示终端在系统信 息读取时间内到标识信息对应的辅小区中读取 CELL_FACH下行多点传输辅小 区配置信息；
生效指示模块 13 , 用于向终端发送配置生效时间， 指示终端在配置生效时 间内根据读取指示模块读取的 CELL_FACH下行多点传输辅小区配置信息， 完 成 CELL_FACH下行多点传输的辅小区的配置。
上述实施例介绍了 RNC采用两种方式指示终端进行 CELL_FACH MP-Tx配 置的实现方式， 当 RNC 指示终端去辅小区中读取系统信息进行 CELL_FACH MP-Tx配置的实现方式还可以更加优化。
具体地， 参见图 17, 为本发明提供的无线网络控制器实施例七的组成示意 图。
本实施例提供的无线网络控制器除了包括如图 11或图 15或图 16中的各个 模块之外 （图 17是在图 11所示的基础上增加定时器发送模块 15的示意图）， 还包括：
定时器发送模块 15 , 用于在配置指示模块发送的下行多点传输配置指示中 携带定时器， 或通过下行无线资源控制信令向终端发送定时器， 以指示终端在 定时器超时前保留其读取 CELL_FACH下行多点传输辅小区配置信息。
这种方式可以避免终端重复读取 CELL_FACHMP T-x配置信息， 以节约配 置时间。 具体实现过程中， 可以对上述配置指示模块 12发送的下行 RRC信令 进一步改进， 使该 RNC不但携带是否配置 MP的指示信息， 以及 MP辅小区的 标识信息， 还携带一个定时器 Tmp给 UE, 或者单独发送一个携带定时器的下 行 RRC信令给 UE, 以指示 UE在定时器超时前保留其读取 CELL_FACH下行 多点传输辅小区配置信息。
以上实施例描述了无线网络控制器的具体实现过程， 实施该无线网络控制 器， 可以在不影响终端在现有 CELL_FACH模式下的较低电量消耗， 较少信令 开销的前提下， 实现高效和灵活的 CELL_FACH MP-Tx 配置， 有利于改善 CELL_FACH模式下小区边缘的终端的数据吞吐速率， 提升用户的体验。
以下将介绍本发明实施例提供的终端的具体实现。
参见图 18, 为本发明提供的终端实施例一的组成示意图。
本实施例提供的终端驻留在如图 4所示的主小区 cell5 ,且处于 CELL_FACH 状态， 其包括： 筛选指示接收模块 20, 用于接收无线网络控制器指示其筛选 CELL_FACH 下行多点传输的候选辅小区的指示；

辅小区上报单元 220,用于在上行无线资源控制信令中将候选辅小区上报给 无线网络控制器；
能力上报单元 221 ,用于将其是否具备 CELL_FACH下行多点传输的能力和 是否具备连接态读取系统信息的能力联合或分别上报给无线网络控制器。
需要说明的是， 能力上报单元 221 在上报以上两个能力时， 可遵循如下规 则：
规则 1 : "是否具备连接态读取系统信息的能力" 可以和 "是否具备 CELL_FACH MP-Tx的能力"进行绑定，也即当 UE支持 "CELL_FACH MP-Tx" 时， UE也应该具备 "连接态读取系统信息" 的能力， 否则 UE都不支持这两个
- , ·
f]匕刀，
规则 2: "是否具备连接态读取系统信息的能力"和"是否具备 CELL_FACH MP-Tx的能力" 之间没有绑定的关系， 能力上报单元 221根据终端自身是否支 持这两个能力单独进行上报。
以图 4为例，假如采用规则 2,该 UE可能会上报支持" CELL_FACH MP-Tx" 能力， 上报不支持 "连接态读取系统信息" 能力。
以上无线网络控制器的实施例中描述了 RNC 有两种方式指示终端完成 CELL_FACH下行多点传输的辅小区的配置。 因此终端的配置指示接收模块 23 的组成也不同。
参见图 22, 为本发明提供的终端的实施例五的组成示意图。
本实施例中， 将描述终端的配置指示接收模块 23和辅小区配置模块 24的 具体组成， 包括：
该配置指示接收模块 23具体包括：
配置信息接收单元 230,用于接收无线网络控制器发送的下行多点传输配置 指示中携带 CELL_FACH下行多点传输辅小区配置信息。
该辅小区配置模块 24具体包括：
配置单元 240, 用于按照 CELL_FACH下行多点传输辅小区配置信息， 完成 CELL_FACH下行多点传输的辅小区的配置。 参见图 23 , 为本发明提供的终端的实施例六的组成示意图。
本实施例中， 将描述终端的配置指示接收模块 23和辅小区配置模块 24的 另一种实现方式。
该配置指示接收模块 23具体包括：
允许指示接收单元 231 ,用于接收无线网络控制器发送的下行多点传输配置 指示中携带的允许配置 CELL_FACH下行多点传输辅小区的指示信息；
小区标识接收单元 232,用于接收无线网络控制器发送的下行多点传输配置 指示中携带的 CELL_FACH下行多点传输小区的标识信息。
该辅小区配置模块 24具体包括：
配置信息读取单元 241 ,用于到小区标识接收单元 232接收的标识信息对应 的辅小区中读取 CELL_FACH下行多点传输的辅小区配置信息；
配置单元 242,用于根据配置信息读取单元 241读取的辅小区的配置信息完 成 CELL_FACH下行多点传输的辅小区的配置。
如图 15所示的无线网络控制器的实施例中， 该无线网络控制器为了发起基 站和终端同步配置， 其下发一个配置生效时间， 因此， 本发明提供一种与之相 应的终端。
参见图 24, 图 24为本发明提供的终端的实施例七的组成示意图。
本实施例提供的终端除包括如图 18所示的各个模块之外， 还包括： 生效指示接收模块 25 , 用于接收无线网络控制器向其发送配置生效时间； 则配置单元 240在配置生效时间内， 按照 CELL_FACH下行多点传输辅小 区配置信息， 与基站同步完成 CELL_FACH下行多点传输的辅小区的配置。
如图 15所示的无线网络控制器的实施例中， 该无线网络控制器为了发起基 站和终端异步配置的流程， 其下发一个让终端自行决定配置生效时间的指示， 因此， 本发明提供一种与之相应的终端。
参见图 25 , 图 25为本发明提供的终端的实施例八的组成示意图。
本实施例提供的终端除包括如图 18所示的各个模块之外， 还包括： 生效自决定模块 26, 用于接收无线网络控制器向其发送自行决定配置生效 时间的指示后， 自行决定一配置生效时间；
则配置单元 240在自行决定的配置生效时间内， 按照 CELL_FACH下行多 点传输辅小区配置信息， 完成 CELL_FACH下行多点传输的辅小区的配置。 如图 16所示的， 无线网络控制器中针对当终端上报其具备 CELL_FACH下 行多点传输的能力但不具备连接态读取系统信息的能力时， RNC采用第二种配 置指示模块 12指示终端完成 CELL_FACH下行多点传输的辅小区的配置的情况 下， 无线网络控制器还需要指示终端系统信息读取时间和配置生效时间， 本发 明提供一种与之相应的终端。
参见图 26, 图 26为本发明提供的终端实施例九的组成示意图。
本实施例提供的终端除包括如图 18所示的各个模块之外， 还包括： 生效指示接收模块 25 ,用于接收无线网络控制器向其发送的配置生效时间； 读取指示接收模块 27 , 用于接收无线网络控制器向其发送的系统信息读取 时间；
则配置单元 242用于在系统信息读取时间内到标识信息对应的辅小区中读 取 CELL_FACH 下行多点传输辅小区配置信息， 并在配置生效时间内完成 CELL_FACH下行多点传输的辅小区的配置。
上述图 23所示的实施例介绍了终端的辅小区配置单元 24采用 RNC指示终 端去辅小区中读取系统信息进行 CELL_FACH MP-Tx配置的实现方式， 该实现 方式还可以更加优化。 其优化方式是： 无线网络控制器还可以在其向终端发送 的下行多点传输配置指示中携带定时器， 或通过下行无线资源控制信令向终端 发送定时器 Tmp, 终端还接收无线网络控制器发送的定时器； 并在定时器超时 前保留其读取 CELL_FACH下行多点传输辅小区配置信息。
参见图 27, 图 27为本发明提供的终端实施例九的组成示意图。
终端除了包括如图 18或图 24或图 25或图 26所示的各个模块之外 （图示 为在图 18的基础上增加定时器接收模块）， 还包括：

配置信息緩存模块 29, 用于在定时器超时前保留读取 CELL_FACH下行多 点传输辅小区配置信息。
具体地， UE的定时器接收模块 28收到 RNC发送的定时器后， 如果配置信 息緩存模块 29已经保存了 MP-Tx辅小区的配置信息（去 RNC指定的辅小区中 读取的）， 那么 UE可以在 Tmp超期前一直保存该 MP-Tx辅小区的信息， 这样 在下次进行 CELL_FACH MP-Tx配置时，就可以节省配置时间和空口信令开销。 本发明实施例提供了的终端， 其可以完成 CELL_FACH模式下配置 MP-Tx 的完整流程。 实施本发明， 在不影响现有 CELL_FACH下 UE较低电量消耗、 较少信令开销的前提下， 实现高效和灵活的配置， 有利于地提升 CELL_FACH 下用户的体验。
本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流程， 是可以通过计算机程序来指令相关的硬件来完成， 所述的程序可存储于一计算 机可读取存储介质中， 该程序在执行时， 可包括如上述各方法的实施例的流程。 其中， 所述的存储介质可为磁碟、 光盘、 只读存储记忆体（Read-Only Memory,
ROM )或随机存储记忆体 ( Random Access Memory, RAM )等。
以上所述是本发明的优选实施方式， 应当指出， 对于本技术领域的普通技 术人员来说， 在不脱离本发明原理的前提下， 还可以做出若干改进和润饰， 这 些改进和润饰也视为本发明的保护范围。
